Marshwalkers

Marshwalkers are a race of sentient bipedal humanoids which probably originated on Xen. They currently hold multiple civilizations on Earth.

Biology
Adult marshwalkers generally range from 6 to 8 feet tall and weigh an average of 175lbs. Marshwalkers lack body fat almost entirely, giving them an incredibly lean and muscular build on their slender bodies. Their legs bend to the side at the knees and end in hooves to maintain stability. They have a rusty brown color on their rough, sandpaper-like skin which can stop small bullets. Their backs are covered in thick wiry hairs which cause heavy irritation when touched. In combat, they perform a half-squat and arch their shoulders, commonly fighting with spears and crossbows. Marshwalkers can run at high speeds on all fours.

Society
Marshwalkers are a rigid caste-based warrior society living primarily in the humid areas of the Great Wastes. They abide a strict class system which includes Warriors, Hunters, Traders/Workers, Masons, and the exiled Outcasts. They are split into hundreds of tribes with a total population around 10,000. Some tribes have allied with the many Synth migrants of the Great Wastes, and some have even opened up trade with humans. One notable marshwalker was "Renfrew", an outcast who accompanied the Grand Excursion through the Wastes to the Beyond and Beyond, never to be seen again.
